Xml parsing within the relevance

Hello All,

I am trying to parse the output of a relevance and want to find the ‘BootStartTime’ and boot ’ BootEndTime’. While i am saving the output in a text file i am able to get the required details.

XML i am using

<Event
	xmlns="http://schemas.microsoft.com/win/2004/08/events/event">
	<System>

The relevance i am using is

( node value of child node of selects "Data[@Name='BootStartTime']" of it,node value of child node of selects "Data[@Name='BootEndTime']" of it) of selects "/Event/EventData"  of xml document of file "C:\Users\hello\Downloads\relevance.xml"
A: 2023-09-11T17:49:30.6301777Z, 2023-09-11T17:51:37.2369645Z .

When i try to parse the output from the relevance i am getting the following error:

`( node value of child node of selects "Data[@Name='BootStartTime']" of it,node value of child node of selects "Data[@Name='BootEndTime']" of it) of selects "/Event/EventData" of ((xmls of records whose (event id of it = 100 AND now - time generated of it < 30*day) of event log "Microsoft-Windows-Diagnostics-Performance/Operational" )) as xml`

E: The operator "xml" is not defined.

Please advice on this ?
